NEW YORK METALLIC BInnE'n r03 smears Application filed March 4,

This invention relates to the manufacture of flexible straps and relates more particularly to the method of applying a reinforcing edge or binder to the edge of a strap for use in connection with wrist watches.

In the manufacture of wrist watches or the like it is desirable to provide means in the form of a flexible bandwhich adapts itself to the contour of the wrist to hold a watch in position.

Various types of employed bands or straps have been a metallic mesh, the latter being more preferable in that the disadvantage of stretching upon becoming moist is avoided. When using a mesh material in the form of a band it is preferable for the-sake of appearance and uniformity to provide the edges of the band with a binding. For this purpose it has been proposed to enclose the edges with metallic sections of. substantially U-shape orcircular form in cross section so formed as to constitute short sections disposed in spaced relation and so disposed that the edgesthereof grip the edge of the strap or band. When the said sections are disposed along the edge of the strap in adjacent relation aflexible protective covering is produced. In applying the binder it is the practice to individually apply the short U-shaped pieces to the strap to build up a flexible protective edge. Although the protective edge produced was of considerable advantage the amount of time and laborinvolve'd in applying the multiplicity of sections, tended to make this construction costly and obviously reduce its value from a commercial standpoint.

' It is an object of the present invention to provide a method of conveniently and expeditiously applying a binder strip to the edge of a flexible member.

Another object of the invention'is to provide a binding strip of articulated sections capable of being applied to the edge of a flexible band as a unit and readily disarticulated into individual units after being secured to the band.

Another object of the invention is to proand it-has been found desirable to use leather or similar material as well as I 1930. Serial u 433,028.

ity of sections held together by frangible connections. I Other objects and advantages of the invention will be appreciated from the following description. together with the accompanying drawings -in which .i Fig. l-is a perspective {view showing a flex: ble strip having a binding edge constructed inaccordanec withthe present invention.-

Fig. 4 is a view similar-to Fig.3 showing a flexible strip composed of leather or other solid flexible material. 1

I Fig. 5 is an enlarged view of a blank before bendmg around the edge of a flexiblev strip. 1 Fig. 6 is aview taken on line"VI--V Iin. Fig. 5, and i Fig. 7 i's-a view taken on lineVIIVII in Fig. 5. '1 s illustrated the invention may -be-'practiced by stamping or otherwise forming from a sheet 9- of -metal a strip 10 shown in Fig. 5 to constitutea plurality of sections 11 connected by frangible separators 12. These separators are only of suflicient strength to hold thesections in spaced relation during handling and breakable when the said'sections are in position gripping the edge of'a grip the body of the strap to which the said sections are attached.

When a strip lO has been applied to the edge of a strap or flexible member 12 and the section bent to grip the strap, the strap may be flexed and such fiexure will cause the separators to break leaving the attached sections in uniform spaced relation to constitute.

a resilient metallic binding. 7

WVhen making a strip of temporarily attached sections it hasbeen found desirable to form the connectors or separators 12 with vide a metallic strip divided into a multiplictheir normal upper surfaces below the norlllO mal upper surfaces of the sections. By reason of this construction the separator pieces when broken by a fleXure of the strap will lie below the surfaces of the sections avoiding any irregularities along the surface of the binding.

It will be evident that by reason of the present invention a binding edge comprising a plurality of disarticulated sections may be provided in a simple and convenient manner from a strip comprising a plurality of articulated sections and that the relative positions or space relation between the sections when secured to an edge may be held symmetric without the care and labor as heretofore necessary.

Although a preferred embodiment of the invention is shown and described herein, it will be understood that modifications may be made therein without departing from the spirit and scope of the invention as set forth in the appended claims.

What is claimed is:

1. The method of applying a metallic reinforcing edge to a flexible strap which comprises forming from a sheet of metal a series of articulated substantially oblong sections, bending the sections to cause their ends to engage opposite surfaces adjacent to an edge of the strap and flexing the strap to disarticulate the sections.

2. The method of binding the edge of a flexible member which comprises forming from a sheet of material a row of articulated W sections, bending the ends of said sections inwardly shaping the sections to enclose the edge of said member and pressing the inwardly bent ends into said member and disarticulating the sections.

In testimony whereof I afix my signature.

CHARLES DUERR.
